The investigation about the minimum sample rate of sampling theorem
Hui Li · 2004
The definitions of the sampling theorem in the different teaching materials are analyzed and their extensive application and practical value in the communication theory are discussed. Though examples of common signal and sine signal, by the frequency spectrum graph and theoretical analysis, the minimum sample rate of the sampling theorem is made clear. The conclusion is that only when the minimum sample rate is more than the double of the band of the signal, can the signal been resumed without distortion. The papers explanation of the minimum sample rate in the sampling theorem provides a theoretical basis for teaching and research.
